I am trying to connect to AWS IOT using X.509 certificate authentication but I am getting SSL Exception in PEM lib and not able to figure out what's going wrong have done the initialization and configuration as per the documentation.
I am using ats endpoint.
Client Initialization:
myAWSIoTMQTTClient = AWSIoTMQTTClient(CLIENT_ID)
myAWSIoTMQTTClient.configureEndpoint(ENDPOINT, 8883)
myAWSIoTMQTTClient.configureCredentials(PATH_TO_ROOT, PATH_TO_KEY, PATH_TO_CERT)
myAWSIoTMQTTClient.connect()
print("mqtt client connection successful")
Traceback:
